Title: Fractional state detector for liquid fuel
Inventor: MIYATA SHIGERU
IPC: G01N25/14
Filed: 1992-05-19
Abstract: PURPOSE:To detect the fractional state of liquid fuel easily. CONSTITUTION:A heater H is thrown into gasoline which is heated at a predetermined temperature by a power supply 10. Consequently, gasoline on the surface of the heater H is evaporated to lower 'the temperature of the heater H. Since the resistance of the heater H decreases to drop the potential at point (b) in a bridge circuit 12, potential at + terminal of an operational amplifier 14 drops. Consequently, the base voltage of a transistor 15 drops to increase the output current of the transistor 15 thus raising the temperature of the heater H and sustaining the temperature at a constant level. The variation of output current corresponds to the fractional state of gasoline and thereby the fractional state of gasoline can be detected accurately and quickly by detecting the variation of the output current. The fractional state can be detected regardless of the using state of liquid fuel.
